Terramar Cotto is a 36" x 36" porcelain tile with rectified edges, which allows a tighter grout joint. The face carries the movement of quarried stone. A matte surface holds light rather than reflecting it. A PEI 4 rating suits heavy residential and light commercial floors. It is frost resistant, so it can run from an interior floor onto a covered porch or patio. A box holds 1 pieces and covers 8.71 square feet. Made in Spain.
